Answer 1

To solve the equation -2x+(-8)=2x+8 using algebra tiles, x equals -4.

Step-by-step explanation:

To solve the equation -2x+(-8)=2x+8 using algebra tiles, we can model the equation by representing -2x with two negative tiles, -8 with eight negative tiles, 2x with two positive tiles, and 8 with eight positive tiles. We can then combine the tiles to simplify the equation.
